BRIEF DESCRIPTION OF THE DRAWINGS

[0019] Figs. la-c top, front and isometric views, respectively, of the invention.
[0020] Figs. 2a-e Diagram views of the sequence of operations.

[0021] An improved system for inserting blind attachments (10) is part of an existing blind attachment apparatus as is known in the art and as such, only the components specific to this invention are discussed in details.
The improved system for inserting blind attachments (10) has an entry point (12) and an exit point (14) for the passage of a seal (16). The seal (16) enters by way of the entry point (12) and continues its guided course by being moved by a pair of servo pullers (18).

[0022] As shown in the series of figures from 2a to 2e, inclusively, a linear drive servo drill (20) running along a drive belt (21) makes a first hole (22) into the seal (16) and, as the seal (16) is moved, the first hole (22) is in position to have a blind attachment (24) inserted therethrough by way of an insertion tool (26). At the same time that the blind attachment (24) is inserted, a second hole (22') is made in the seal (16) by having the servo drill (20) moved at the appropriate location as per fig. 2b, for example. The other figures of the figs. 2a-e sequence show that the seal (16) and the servo drill (20) both move at the same time, which forces the servo drill (20) to adjust so as to drill holes (22, 22', 22", 22"') at the appropriate locations as the seal (16) positions itself under the blind attachment insertion device (26) which is itself stationary. An entry and an exit cutter (28, 30) cut the seal (16) to length.

[0023] The servo drill (20) is a known device used in many fields and the insertion tool (26) is similar to those currently in use.

[0024] The invention lies in the motion of the servo drill (20) running on a drive belt (21), in cooperation with the movement of the seal (16) along with the concurrent insertion of the blind attachment (24) by way of the insertion tool (26).

[0025] As to a further discussion of the manner of usage and operation of the present invention, the same should be apparent from the above description. Accordingly, no further discussion relating to the manner of usage and operation will be provided.

[0026] With respect to the above description then, it is to be realized that the optimum dimensional relationships for the parts of the invention, to include variations in size, materials, shape, form, function and manner of operation, assembly and use, are deemed readily apparent and obvious to one skilled in the art, and all equivalent relationships to those illustrated in the drawings and described in the specification are intended to be encompassed by the present invention.

[0027] Therefore, the foregoing is considered as illustrative only of the principles of the invention. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation shown and described, and accordingly, all suitable modifications and equivalents may be resorted to, falling within the scope of the invention.
